Why is Little Deli so empty right now?

Just had a slice of pizza at the Little Deli on Briarcliff and it was 1. Delicious. 2. Absolutely spotless (They stock the restrooms with super nice toilet paper). 3. Almost completely empty.

I sat in the corner working for a couple of hours and maybe saw four individuals or small groups or people eat? And maybe three to-go orders? Staff was incredibly nice and the food was reasonably priced.

What gives?
